Applications of 123639-61-2
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Protecting reagent for the glutamic acid side chain in solid-phase peptide synthesis | Used in Fmoc-based solid-phase peptide synthesis (SPPS) to selectively protect the γ-carboxyl group of L-glutamic acid, preventing side reactions during peptide chain elongation; the Fmoc group protects the α-amino group, while the benzyl ester (OBn) protects the γ-carboxyl group—both groups are orthogonally removable |
| Pharmaceutical R&D | Key building block for synthesizing peptide-based drugs and intermediates | Applied in the synthesis of therapeutic peptides containing glutamic acid residues (e.g., hormone analogs, antimicrobial peptides, targeting peptides), ensuring controlled handling of side-chain functional groups prior to coupling, cyclization, or modification steps |
| Fine Chemicals | Standard starting material for custom synthesis of chiral amino acid derivatives | Enables stepwise deprotection and structural modification via selective removal of the benzyl ester group using palladium-catalyzed hydrogenolysis or a trichloroacetic acid/anisole system, or removal of the Fmoc group using piperidine/DMF |
